What are the best credit cards?

The best credit cards for me are not necessarily the best cards for you. I don’t find I’ve changed my spending habits much in retirement, but being retired has meant I can spend a bit more time trying to optimize my credit card holdings to maximize benefits to me. One thing that I value above all else is cold, hard, cash. I don’t like “points” cards because understanding what kind of ROI I’m getting is nearly impossible, and always subject to the whims of a points to dollar conversion rate that can be changed at any time. I’m now holding three different credit cards, all of whom pay cash back, and all of them have their place in my spending universe.

Primary Card: Rogers Red World Elite Mastercard

Read about it here. As a Rogers customer1, this card is really the best possible card for my needs:

  • No fees
  • 2% cash back on everything, paid as a reward credit that you then immediately apply to subsequent card purchases; this reward credit is multiplied by 1.5 if you apply it to a subsequent card purchase for a Rogers service.
  • 3% cash back on USD purchases, which erases the 1.5% FX fee charged, and then some
  • Travel insurance, purchase insurance, etc etc
  • Free supplementary cards

The problem with this card is that its credit limit is a bit low; I even asked for an increase and was denied2.

The other problem with this card is that it’s not tied to my normal banking, so I have to pay it manually3. And it only offers a login for the primary card holder, which isn’t ideal.

Secondary Card: CIBC Costco Mastercard

Read about that one here. This one is actually a conversion from another CIBC card I had. Converting a card from one kind to another means you don’t lose your credit limit, which was the main appeal here. I am a Costco member, so this is a good second choice for my needs:

  • no fees
  • 1% cash back on everything except 2% back on gas and Costco.ca, and 3% back on Costco gas4 and restaurants5
  • Cashback paid annually in the form of a Costco gift certificate
  • Travel insurance, purchase insurance etc etc
  • Free supplementary cards

The travel card: Wealthsimple Visa

I’ve been on the waitlist (like many people) for quite a few months for this card now. I finally got my card when I called their support line to query about why a transaction on their prepaid Mastercard6 failed to complete. (Turns out there’s a daily limit on that card that can’t be modified). Anyway, the helpful agent offered to put in a good word for me and a few days later, I was able to successfully apply for the card and immediately download it to my phone7.

The Wealthsimple Visa’s features are a lot like the others:

  • no fee (if you have enough assets with Wealthsimple)
  • 2% cash back on everything, paid into your account every month
  • travel insurance, purchase insurance, etc etc
  • and…most importantly for me, NO foreign exchange fees for any currency

With no foreign exchange fees, Wealthsimple’s Visa becomes the go-to card anytime I’m travelling to a non-US destination. It also becomes my primary card in the event that I cut ties with Rogers, since the only thing the Rogers card does better than the Wealthsimple card is paying for Rogers services.

The Wealthsimple card had a better credit limit than the Rogers card right out of the gate (I guess it helps that I had hard assets with them) but inexplicably does not have the concept of a secondary card, so my spouse is currently locked out of that benefit.

The card that got cut: the CIBC Aventura USD Gold Visa

This was a card I had for a few years when US travel was a more frequent (desirable?) option. It’s not a bad card, especially if you frequently transact in USD, but with two other cards that offered “good enough” coverage on USD purchases, I felt it was no longer needed. And (I forgot this) when I canceled my almost-never-used CIBC USD checking8 account, I lost the “no-fee” aspect of this card. At a cost of zero I might have been convinced to hang on to it “just in case”, but with a $35 annual fee (USD) it was no longer required. An hour long wait on hold with CIBC telephone banking was all it took9.

What card is used when?

  • For foreign currency transactions, Wealthsimple Visa card is best. Rogers card also a good option if USD.
  • For Costco gas and restaurants, Costco card is best.
  • Anything else, Rogers
  1. Internet, television, home phone, if you’re curious. 2 year contract which I’ll probably break at the earliest opportunity 😉 ↩︎
  2. Admittedly, this hurt my feelings a bit. ↩︎
  3. I could set up a PAD, but I trust Rogers about as much as they trust me, it seems. ↩︎
  4. There’s no advantage to actually shopping at a Costco store with this card, which seems weird. My weekly Costco grocery run is paid for with my Rogers Mastercard, since I get 2x the cash back <shrug>. What’s more, the Costco I usually frequent doesn’t have a gas station, and I’m not really willing to make a special trip to go get it — my CAA/Shell combination is about as good. ↩︎
  5. These 2% and 3% rewards have annual caps, but I got bored trying to memorize them ↩︎
  6. Part of Wealthsimple’s chequing account, a good product, in my view ↩︎
  7. Great timing too, since I was in a foreign country at the time. ↩︎
  8. I use American spelling here because (a) that’s how CIBC spells it and (b) it really is a US-domiciled account ↩︎
  9. Writing that sentence has confirmed for me how low my standards for customer service have become. ↩︎

Can I take advantage of higher US interest rates?

I have a dedicated non-registered account in my retirement portfolio that is the cash cushion for VPW’s decumulation strategy. You can read about the details of how I currently get paid in retirement here.

That non-registered account holds about 85% Canadian dollars, invested in ZMMK, with the remaining 15% invested in ICSH. Both of these ETFs are very short-term bond funds and give me a slight advantage over investing in zero-risk HISAs. ZMMK and ICSH are part of my ETF all-stars lineup, and I track HISA rates on a monthly basis.

The fact is that US interest rates are a lot higher than Canadian interest rates, almost 2% higher as of July 2025. It seems to me that I should take advantage of that fact. Taking advantage of this situation would mean selling some ZMMK, performing Norbert’s Gambit with the resultant cash, and then buying ICSH. There are costs involved at every step of the way1:

  • Selling ZMMK means I’ll get dinged with the bid/ask spread2
  • Performing Norbert’s Gambit costs $9.95 plus HST on Questrade to do the necessary journaling
  • There will be bid/ask spreads to pull off the Gambit…once when buying DLR, once when selling DLR.U
  • Buying ICSH means another bid/ask spread

So at what point is it worth it? Let’s do a bit of math using the following assumptions:

  • The delta between US and Canadian rates is 1.8% in favor of the US rate. That’s an annual rate, and I’ll just divide by 12 to get a monthly rate3.
  • The bid/ask spread for DLR per the ETF fact sheet is 0.1% on the CAD side and 0.07% on the USD side
  • The bid/ask spread for ZMMK is 0.02% per its fact sheet
  • …and the bid/ask spread for ICSH is 0.02% as well per its fact sheet
  • No change in the FX rate for the duration of this exercise4
  • No fees to trade DLR, DLR.U, ZMMK or ICSH5

So for various amounts, the time to profitability6 of doing the Gambit looks like this.

$ CAD changedJournaling Fee7DLR Spread Fee8ZMMK/ICSH spreadTotal costTTP9
$1k$12$1.70$0.40$14.10~10 months
$10k$12$17.10$4$33.10~10 weeks
$100k$12$170$40$222~6 weeks

So clearly, for amounts around $1k this isn’t such an attractive proposition as the costs will take a fair bit of time to be negated by the bump in interest rates. For larger amounts, I’d say it’s worth it. Given ZMMK hasn’t yet paid out its dividend for the month, I guess I’ll wait until I’m ex-dividend (July 30, 2025, per the fact sheet) before doing this transaction.

  1. I’m also ignoring the tax on any capital gains I might pull off. It will be quite small, and will be close to 0. ↩︎
  2. Bid/ask spread is the difference between what the price holders are willing to sell at versus the price offered by a buyer. For ZMMK this is typically 1 cent. ↩︎
  3. Whether this delta continues to hold is anybody’s guess. ↩︎
  4. Which, admittedly, has no hope of being correct. If you do this sort of thing frequently enough, it ought to even out over time. ↩︎
  5. This is true at Questrade. YMMV with your broker. ↩︎
  6. Henceforth “TTP”, naturally ↩︎
  7. Adding HST and rounding ↩︎
  8. Buying DLR is 0.1% and selling it is 0.07% ↩︎
  9. Investing all holdings at 1.8% annual rate of return ↩︎
